One of the more commonly used is investment casting, also known as lost wax casting: choose appropriate investment materials (such as paraffin wax) to manufacture investment;Repeat dipping refractory coating and sand spraying on the investment mold, hardening shell and drying;Then melt the internal mold to get the cavity;Calcined shell to obtain sufficient strength and burn off the residual investment materials;Metal materials required for pouring;Solidification cooling, dehulling after sand cleaning, so as to obtain high-precision finished products.According to the product needs or heat treatment and cold processing and surface treatment.

Process flowWax mould (wax mould) - wax mould) - wax - wax - wax inspection - group tree (wax) -system shell (first pulp, shower sand, recontamination, and final modeThe shell of the shell is the drying wax (steam removal wax) -" steam removal wax) "-" the baking of the wax" -" mould shell roaster "- the process of the casting (casting the steel water in the mold casing)Casting and casting rod cutting separation - the first inspection of the grinding gate -the hair embryo inspection) -the finished inspection of -the finished product inspection -the finished product inspectionThe casting production process is generally such that it can be divided into pressure wax, shell, casting, back processing and inspectionPressure wax includes (pressure wax, paraffin wax, group tree)The wax -is used to make waxModified waxThe group tree -is the tree of the treeShell includes (hanging sand, hanging pulp, drying)The casting includes (roasting, the process of the analysis is also called the light spectrum, pouring, shock casing, cutting gate, grinding gate)After treatment includes (sand blasting, blasting, correction, pickling)Inspection includes (wax inspection, preliminary inspection, medium inspection, finished inspection)Above is the process of precision casting of precision foundry
